[dev] passwd - crypt-md5

| No, it is the standard system crypt but with a 12 character salt instead of
| 2 characters used for DES.

Is crypt-md5 the best name?  If i was a newbie i would assume that my previous
explanation was the correct one.  How about changing doing something like

crypt-old
crypt-new

Or something that would make it easier to understand that differences.  And also
make sure you change the docs at the top of backends.php.dist so that everyone
knows what the possible encryption types are.  And an explanation of the fact
that is what is used in /etc/shadow and nss_mysql would help people figure out
what encryption type to use.

LDAP always seems to be the misunderstood one :)  I think its nice that it
allows you to use different types of encryption.  But after looking at the
drivers I think you are right.
